Abstract
A device for releasing reactant (R) into the exhaust gas stream (A) of an internal combustion engine, includes a reactant injection unit (20), a reactant delivery unit (12) for delivering reactant (R) from a reactant reservoir (14) to the reactant injection unit (20), and a heating unit (18) for heating reactant (R) delivered by the reactant delivery unit (12) to the reactant injection unit (20). The reactant injection unit (20) is switchable as a function of a reactant pressure generated by the reactant delivery unit (12) between an open state for releasing reactant (R) and a locked state for preventing the release of reactant.
